The well-known, rank-odoured, showy-flowered Jimson-weed's chief occupation seems to be in hiding the unsightly scars created by ruthless man, in the shape of refuse piles, public dumps, and neglected barnyards. The dried leaves are smoked in a pipe by people seeking relief from asthma. The fruit is poisonous, and the flowers have been known to produce serious results when held in the mouth. This plant is a stout, smooth, bushy annual with a coarse green stem, growing from one to five feet high. The large, thin, smooth leaves are pointed-oval in outline with an irregular, wavy, toothed margin. They have a veined surface, and are long stemmed. The large, showy, Morning-glory-like white flowers, which open late in the afternoon, have a heavy odour, and grow erect and solitary from the forks of the branches. The large, tubular calyx is five toothed and angular. The five-pointed, funnel-formed corolla has a deep throat and contains five stamens and a pistil. The Indians call this species the "White Man's Plant"

It blossoms from June to September, and ranges from Nova Scotia to Minnesota, and south to the Gulf States.
